skyJake has updated the Jdoom site with an update from last week's release. It's maintenance release, Version 1.13.1, and some of the fixed bugs include:

Model skins are precached by default (cvar rend-model-precache). Should be a noticeable improvement when the game doesn't any longer pause slightly each time a skin needs to be loaded.
Rendering of particles can be made a little faster with the cvars rend-particle-diffuse and rend-particle-visible-near.
View and player weapon bobbing can be freely scaled with the cvars view-bob-height and view- bob-weapon. Try forcing the former to something like 10 (bunny simulator :-)).

Head on over to the Jdoom site and grab the latest version of the pretty port.
